THOMAS LAIT, OF MEDICINE HAT, ALBERTA, CANADA.

OPERATING MECHANISM FOR BINDER SAILS OR FANS.

Specification of Letters Patent.

Patented Oet. 22, 1907.

Application filed December 29,1906. Serial No. 349,958.

To all whom il vmuy concern:

.Be it known that I, THOMAS LAIT, a subject of the ling of GreatBritain, residing at Medicine Hat, in

the Province of Alberta, Canada, have invented certain new and usefulImprovements in Operating Meehanism for Binder Sails or Fans, of whichthe following is a specification.

My invention relates to improvements in operating mechanism for bindersails or fans7 and the objects of my invention are: firstly, to providean improved construction for the standard supported from the grainwheelend of the binder so as not to interfere with the movement of the grainand so prevent any portion of the binder from becoming clogged thereby,and secondly, to provide improved means for releasing the standard atthe grain-wheel end of the binder and the standard at the master-wheelend of the binder by one operation of the foot.

The construction of my invention will be hereinafter fully described,and the parts I claim as new will be set forth in the appended claims. c

The prescnl appication covers an invention which is an improvement on myoperating mechanism for binder sails or fans, Iiled May 31st, 1906,under Serial Number 319,475.

Figure 1 is a front elevation of my improved reel and the mechanism foroperating same, showing same attached to the platform of a binder,portion of which only is shown. Fig. 2 is a side elevation of myimproved mechanism for operating the reel, showing same supported by abinder, portion of which only is shown. Fig, 3 is a verticalcross-section through the platform of a binder machine, showing a sideelevation of the standard supported at the grain-wheel end of thebinder, and means for supporting same. Fig. 4 is an enlarged rearperspective view of the mechanism for rotating the reel, and showing thepreferred means for supporting same on the standard hinged to themaster-wheel end of the binder platform, only portion of said standardbeing shown. Fig. 5 is an enlarged section on the vertical plane passingthrough the line ab, Fig. A1, showing portion of the driving means forthe rcel, and showing means for raising and lowering same. Fig. (i is anenlarged vertical section through the operatingr mechanism at the lowerend of the standard hinged to the master-wheel end of the binderplatform. Fig. 7 is an enlarged vertical section through portion of thestandard hinged at the grain-wheel end of the binder, showing the pinionsecured to the reel-shaft and coperating therewith. Fig. 8 isan'enlai-ged plan view of the gearing for rotating the reel.

Fig. 9 is a horizontal cross-section on the line c-d, Fig. 3, throughthe standard at the grain-wheel end of the binder, and the bracketoperating therearound. Fig. l() is a plan view ofthe lever 52 pivoted tothe seat board. Fig, ll is an enlarged perspective view of'the springsecured to the platform and co-acting with the standard hinged at thegrain-wheel end of the binder.

In the drawings like characters of reference indicate correspondingparts in each figure.

2 is the platform of the binder which is constructed after any wellknown manner.

Hinged at 3 to the bracket 4 which is suitably bolted to themaster-wheel end of said platform is a standard 5 over which operatesthe sleeve 6. According to my preferred form of construction shown, saidsleeve is provided with a wing 7 to which is secured or formed a partthereof the bracket 8 in which has bearing at one end the reel-shaft 9.This reel-shaft extends to the grain-wheel end of the binder and haskeyed thereto at this end a pinion 10 which operates in the gear toothedrack 1I with which the standard I2 (to be hereinafter particularlydescribed) is provided, which standard is hinged at 13 to any suitablesupport M at the grain-wheel end of the binder.

131 is a bracket operating over the raclcprovided portion 103 of thestandard 1 2 and in which has bearing the portion of the reel-shaft 9passing therethrough.

Loosely mounted on the reel-shaft 9 is the reel 16 which may be of anysuitable construction, and provided with the usual sails orfans.According to the construction shown of this reel, same comprises asleeve 17 provided at each end with spiders 1,8 to which is suitablybolted the arms 19 which carry the fans or sails 20.

2l is a gear-wheel secured to one of the spiders 18 and meshing with thepinion 22 keyed to the shaft 23 (which has bearing in the bracket 8) andwhich shaft is provided with a bevel pinion 24 which meshes with thefront face 25 of the double bevel gear wheel 2G which is mounted on thestub-shaft 27 secured to or formed a part ol the front portion 28 of thebracket 6.

Meshing with the front face 25 of the double bevel gear-wheel 26 is abevel pinion 29 through which passes a shaft 30 which rotates said bevelpinion. 29. This bevel pinion is held in mesh with the front face 25 ofthe double bevel gear-wheel 2G by any suitable means. According to theconstruction shown, I show a bracket 31 for this purpose secured to orformed a part of the bracket 6. Where the shaft 30 passes through saidbracket 3l, same is provided with holes 32 larger than said shaft sothat same will not come in Contact therewith. It will be understood thatwhen the bracket 6 is raised and lowered on the standard 5 (by meanshereinafter described) that the parts above described will movetherewith and will be held in a constant position in relation to eachother. The shaft 30 is coupled by a universal joint 33 to the stubshaft35 held in the portion 36 of the bracket 4. The construction justdescribed for connecting the shaft 30 with the stubshaft 35 is of coursewell known. This stub-shaft carries a bevel gearywheel 37 which mesheswith a bevel pinion 38 keyed to lcured to or formed part ol the wings 7and 48.

a shalt 39 journaled in said bracket 4. By means ol a sprocket-wheel 4()suitably supported on said shalt 39 and the sprocket-chain 4l coperatingtherewith (which is shown dotted) energy is transmitted (by suitablemeans not shown) from any suitable source of supply. to thesprocket-wheel 42 journaled at the upper portion of the member 43 andnear the binder deck so as to rotate the reel I6. In order to raise andlower said reel so as to enable same to handle all kinds ol' crop, Iprovide the following means: Keyed to the reel-shalt 9 is a pinion 44which meshes with the gear toothed rack 45 with which the standard 5 isprovided. Upon referring to Fig. 5 it will be seen that this pinion 44is preferably housed by the iront portion 28 oi the bracket 6. Featheredon the reel-shalt 9 is a toothed clutch 46. 47 is a bracket secured toor formed a part ol' the wing 48, secured to or formed a part ot' thebracket 6, in which has bearing the master-wheel end ol the reel-shaft9, Loosely mounted on this reel-shaft is a bevel pinion 49 which is heldconstantly in mesh with the back face 50 of the double bevel-gear-wheel26. The bevel pinion 49 is constructed after any oi the well knownmanners in order that the toothed clutch 46 may coperate therewith.Extending adjacent to the driverls seat (the post 51 ol which only isshown) is a lever 52 of any suitable construction. In order that thislever may cop erate with the bracket 6, same is constructed with aforked end 53 which is pivoted at 54 to the ears 55 se- By pulling thelever 68 connected by the rod 69 to the clutch lever 58 (which ispivoted by the lugs 59 to the bracket 6) the clutch 4G is moved so as tobe coupled tothe bevel pinion 49 thus rotating the reel-shaft 9 and thepinions 44 and 10 and raising up the sleeve 6 and said reel. Thebevel-pinion 29 it will oi course be understood has union with the shaft30 in such a manner as to permit of its longitudinal movement thereon,as will be understood by one skilled in this art. As soon as the reelhas been raised to the proper height., the clutch 46 is thrown out ofgear as will be understood.

From the construction and operation of the parts before described, itwill be understood that the reel l6 is continuously revolved. As beforedescribed,

through the movement of the clutch lever 58 the mechanism for raisingthe reel is thrown into gear. During the throwing of this mechanism intogear, the nose 6() of the clutch lever 58 presses against the lower endof the lever 61 (pivoted by the ears. 62 to the bracket 6) and moves theend of the nose 63 of said lever out of the notch 64. But this movementdoes not move said nose far enough to escape the teeth 65, thus stilllocking the bracket 6 and its connected parts to the standard 5. lhenthe mechanism for raising said bracket and the reel is actually inoperation, then the nose 63 is moved upward out of locking engagementwith the rack 66. By thus positively throwing into gear the mechanismfor raising the reel prior to the unlocking of the bracket 6 and partscarried thereby from the standard 5, it will be understood that there isno possible chance of said reel and bracket 6 and connected parts fromfalling. From the foregoing, it will be understood that the nose 63 ofthe lever 6l is always in position to engage with one of the teeth 65immediately upon the throwing out of gear` of the reel-raising mechpartsto the standard 5. The notches 64 and teeth 65 constitute the toothedrack 66 secured to or formed part of the standard 5. It will be noticedthat the teeth 65 are sloped inward so that the nose 63 will slipthereby and not lock the bracket 6 to the standard 5 during theoperation of the reel-raising mechanism. By means ol the spring 67 heldbetween the lower end of the lever 6l and the bracket 6, it will beunderstood that the lever 6l will be positively held in normal position.Upon release of the pull of the rod 69 against the clutch lever 58 itwill be understood that by reason of the position oi said clutch leverthe spring 67 will move said clutch lever into the position shown inFig. 4, thus throwing the clutch 46 out oi contact with the bevel-pinion49 thus stopping the rotation of the pinion 44. In order to lower thereel, the grip 56 (pivoted to the lever 52) is pulled so that by meansof the rod 57 connecting same to the lever 7 0 (pivoted by the ears '71.to the bracket 6) said lever 70 is moved so that its nose 72 willdepress the lower end of the lever 6]. and move its nose 63 out ot oneof the notches 64 and far enough to escape the teeth 65. These parts areheld in this position while the lever 52 (which is connected as beforedescribed to the bracket 6) is tilted around its support 73 which ispivoted to the seat-board 75. Upon release of the grip 56 it will beunderstood upon inspecting Figs. 4 and 5 that the spring 67 will movethe levers 6l and 70 back to normal position.

In order to provide for the necessary movement oi the standards 5 and12, the support 73 is pivoted as shown at 76 to the seat-board 75 and isadjustably held in different positions by any suitable means, with whichmeans cooperates means for locking and unlocking the standard 12,hereinafter particularly explained. For thepurpose of adjustably holdingthe seat-board 75 in any set position, I pivot to the lower portion ofsaid support a bell-crank lever 77 which controls a spring-controlledbolt 78 which engages with the toothed quadrant 79 suitably secured tothe under side of the seat-board 75. In order to release the bolt 78from the quadrant 79, I provide a toot-lever 8O pivoted at 81 to theseat-board, and connect the lower end of same by means of a rod 82 tothc bell-crank lever 77. As this foot-lever is in close proximity tothedrivers foot it will be understood that by moving same in the directionindicated by arrow, the support' 73 will be unlocked and may then bemoved into the required position. Upon release of pressure from thefoot-lever 80, the mechanism connected therewith will of course lock thesaid support in position. Where the lever 8O .and support 73 operatethrough the seat-board 75, I

provide suitable longitudinal slots 83 and 84.

85 is any suitable brace lor the lever 52.

It will of course be understood that the standard 5 may be braced orsupported by any suitable means. According to the construction shown, Iprovide a stayrod 851 hinged at its lower end 86 after any suitableconstruction to portion of the frame 87 of the binder. The upper end ofsaid stay-rod is secured to the cap 86 with which the standard 5 isprovided.

89 is any suitable rein-support secured to or formed a part of the cap88, i

In case the driver should be careless and leave the reel-raisingmechanism in operation too long, and in anism and thus lock the bracket6 and its connected l order to prevent the damaging of the parts, Isecure to 130 or form a part of said cap SS a downwardly-depending arm90, the lower end ol` which is in the path of movement of the outside ofthe clutch lever 5S. Upon referring to the drawings it will be seen thatwhen the bracket 0 is raised up high enough, the clutch lever 58 will bemoved in contact with the arm 00 and same is cmistrtufted so that. thislever is thrown into the position shown in Fig. 11, thus throwing thereel-raising mechanism out ot' gear and permitting the lever (il to lockthe sleeve (i ol' the reel to the standard 5'. 'lhus automaticallythrowing the reel-raising mechanism Vout of `gear at certain timesprevents the mechanism from being damaged.

Upon inspecting Figs. 5 and 7, itwill be seen that the pinions Llli and10 are of the same size, Now from the operation of the parts beforedescribed, it will be understood tl at when the pinion Liat is rotatedto raise or lower the master-wheel end of tle reel, the pinion 10 islikewiso operated in th e required direction and thus raises or lowersthe grain'whcel end of said reel (through the medium of the rcel-shaft9) and the same distance that the master-wi1eel end of the reel las beenraised or lowered, thus keeping the ians or sails 20 in such positionthat they will always operate parallel to the cutterbar. The standard l2will be preferably of the same lzeigl' t as the standard 5. By hingingthese standards as before described. it will be understood that thebacki'ard and forwart'l movement of the rcel is provided for.

[n order to pre vent the jarring of the machine accidentally throwingrthe Clutch. 40 into gear with the bevelpinion ll0, l provide a spring 02connected at one end to tire bracket (i and at the other end to the endof the clutch lever 58 engaging with the clutch 40. Upon referring toFig. 4, it will be understood that the action of tt e spring 02 keepsthe clutch -tt in the position shown so that the reel-raising mechanismwill be out of gear. From the foregoing specification, it will beunderstood that the spring 02 assists the spring G7 in its action, atcertain times, against the clutch. lever 58. "li e spring 07 reallyexerts no pressure against tlvc clutch lever 58 when the lever til isdepressed by the lever 70, so therefore an additional spring forpositively holding the clutch 40 out ol' gear, at certain tiines, withthe bevelpinion 40, would appear to be necessary.

.ln my before-rmntioned application, the standard 1.2 was constructedperpendicular throughout its length, and l found tlat same was liable tocause the grain to clog therearouinl. New in my improvement, thestandard l2 is provided with a lower portion 100; a toot! ed portion|0l; a horizontal portion 102, and a. rack-provided portion 103. Byconstructing my standard as shown in liigs. 2 and 3 of the drawings, itwill be understood that by reason of the gap or space between theportions 100 and 102, the grain will not clog against said standard 'Ite toothed portion 101 is of course concentric to thc pivotal point 13 ofsaid standard.

104 is a suitable standard secured to the platform 2, as shown..

105 is a bracket by means of which the toothed portion 101 of thestandard 12 is held in relationship to the standard 1.04. .lbe bracket105 is suitably secured to the standard 104.

10o is a dog pivoted at 1.07 to the standard 104, and is designed toengage with the teeth .108 of the toothed portion 101 of the standard1.2.

109 is a spring which connects the dog 106 to the standard 104 and keepssaid dog in engagement with the teeth 108.

When the driver operates the lever 80 in order to unlock the supports73, I provide a means whereby thc same movement of the lever will unlockthe standard 12. 1n other Words, the movement of the lever 80 willunlock the standards 5 and 12 at the same time and thus permit same tobe moved in the required direction. When the lever 80 is moved in thedirection indicated by arrow, this movement, besides operating the rod82 so as to release the bolt 78 from tie quadrant 7 9, operates the dog10G so as to move same out of contact with the toothed portion lOl ofthe standard V12, through the means now to be described.

1.10 is a flexible connection passing over the pulley 111 supported inthe seat-board 75, and connecting the lever 80 with a rod 112.

113 is a flexible connection passing under the pulley 114 suitablysupported'from the rear of the platform 2, and by means of which the rod1.12 is connected with the rod 11.5 which preferably lies at the back ofthe platform 2.

Passing under the pulley 117 (which is likewise suit ably supported atthe rear of the platform 2, as is the pulley 11?) is a tiexibleeonnectionrllti by means of which the rod 115 is secured to the rod 118which is connected to the dog 10o.

By the means just described, it will be understood ti at one movement ofthe lever 80 will unlock the standards 5 and 12. The spring 109 willreturn the dog 106 of the means intermediate same 'and the lever S0 backto normal position so soon as pressure is relieved from the lever S0.The bracket 105 will prevent undue side motion ofthe standard 12.

1i' desired l may provide a brace 119 bracing together the portions 102and 103 of the standard 12. 1n order to permit free movement of thebracket 1.3, the rear of same is eut away as shown at 120 so as not tointerfere with the brace 119.

121 is a flat spring which is suitably secured as at 1.22 to theplatform 2. Wlen in its normal position, the portie-n 100 of thestandard 12 will rest upon the spring 121. The said spring is soconstructed that it exerts energy to assist the operator in moving thestandard 1.2 around its pivotal point 13.

It will of course be understood that the lever 80 and mechanismcontrolled thereby is only operated when the standards 5 and 12 aremoved around their pivotal points 3 and 13.
